CAN-BODY-FLANGING MACHINE.

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed November 23- 1906. Serial No. 344.697-

To all whom it may concern:

Be it known that I, SWAN TEVANDER, a

.4 citizen of the United States, residing in Maycan'body flangingmachineof a simp .and perfect flanges,

form against the wood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in 'Oan-Body-Flanging Machines, of which the following is a specification.

My invention relates to improvements in flanging machines for flanging the bodies of cans or other vessels preparatory to seaming.

The object of my invention is to provide a e,s trong, eflicient and durable construction by means of which the bodies of sheet metal cans or other vessels may be rapidly and cheaply flanged, and by means of which the can bodies may be provided with uniform, true so that hermetically tight and perfect double seams may be formed by and between the seaming flange of the can body and of the can cover.

My invention consists in the means I employ to practically accomplish this object or result. That is to say, it consists in connection with a-rotatable flanging tool or roller, of a rotary flanging head or chuck adapted to receive thereon the open or mouth end of the can body, and a yielding or cushioned sup orting ring mounted on the rotary flangmg body and support the same in true circular thrust of the flanging tool or roller while permitting the can body to yield or move with the flanging roller in respect to the flanging head as required in carrying out the flanging operation. My invention also consists in the novel construction-of parts and devices, and in the novel combinations of parts and devices herein shown and described.

In the accompanying drawing forming a part of this specification, Figure 1 is a side elevation of a can body flanging, machine embodying my invention, an -Fig. 2 is a plan view. ig. 3 is an end elevation. Fig. 4 is a detail vertical section on line 4-4 of Fig. 2' through ing or movable canbody supporting rings or chucks; and Fig. 6 illustrates a modificationin which only one flanging head and only one flanging tool or roller is employed.

In the drawing, A represents the frame of the machine, B is a rotary flanging head having a flanging shoulder b adapted to fit inside ead and adapted tofit inside the can Fig. 5' is a detail central sectionthe flanging head showing the yield the mouth a: of the body X of the can or vessel about to be flanged and cooperate with .the rotatable flanging tool or roller Oin turning the flange m upon"the open or mouth end of the can body as the flanging tool or roller'O is moved radially toward the rotating can body on the flanging head B.

Iniorder to cause-the flange to be truly, uniformly and perfectly formed on the can body, I provide the rotary flanging head B with a cushioned porting ring or chuck D'which fits inside t body of the can or vessel and supports it in true circular shape during the flan in operation. The supporting ring orc 110 D is furnished with a cushion or spring D preferably of rubber, and surrounding the hub b on the flanging head B which cushions the ringor gives it a spring support and enables it to yield against the thrust of the flanging tool or roller C and move therewith as this tool or roller moves toward the flanging head B. The rotary flanging head B is also provided with a guide ring or disk D to keep the cushion chuck ring D in lace and guide its movement. The rotary flhnging head B for the end of the can body to abut against and limit the width of the flange to be formed on the can body. The rotary flanging head B is preferably adjustably connected to its rotating shaft B by jam-nuts B B which engage screw threads B on the overhangin end of the shaft B The flan ing head is continuously rotated by a pulley B on its .shaft through a suitable belt.

The flanging tool or roller O is preferably adjustably connected to its rotatable su porting shaft O by means of jam-nuts O O which engage screw threads C on the shaft 0 The rotatable shaft 0 is journaled in suitable bearings F on a rocking or swinging frame at and having an operating arm f connecte by a link f With a foot treadle f by Which the rocking frame is depressed to move the flanging tool or roller O against the can body on the rotating flangin head B. A link H and spring H serve to 'ft or return the swinging frame F to its upper or normal position. i

To ada t the machine to simultaneousl flange bot ends of the can body X, the sha t B is provided with two flanging heads B adapted to be adjusted apart according to the movable or yielding sulphas a flange or shoulder 11 to serve as a stop frame F pivotally connected to the main length of the can body X by the screw threads B on the shaft B and the shaft C one Hanging tool or roller 0 on the shaft C as shown in the modification illustrated in Fig. 6., In this modification, the Hanging roller shaft C is provided with a disk C overlapping the can to hold it in place on the Hanging head B and supporting ring D, and the shaft B is providedv with a supporting disk B which fits inside the can to support its outer end.

I claim 1. In a flanging machine, the combination with a Hanging head, of a Hanging tool or roller movable to and from the Hanging head and a movable cushion chuck ring on the Hanging head fitting inside the body of the vessel to be flanged to su port the vessel in true shape during the ilanging operation against the thrust of the Hanging tool or roller, a Hanging head shaft and a supporting device for the outer end of the'can on the outer end of said Hanging head shaft, substantially as specified.

2. In a Hanging machine, the combination with a rotar Y Hanging head, and a rotatable Hanging too or roller movable to and'from the Hanging head, and an opposing spring supported or cushioned supporting ring or chuck for the can body mounted movably on the Hanging head and adapted to fitinside the mouth of the vessel to be Hanged and op o'se 'the thrustof the Hanging tool or rol er, a Hanging head shaft and a supporting device for the outer end of the can on the outer end 'of'said Hanging head shaft, substantially as s ecified.

3. The com inatidr with a Hanging tool or roller, of a Hanging head arid a movable supporting ring on the Hanging head and fitting inside the mouth of the vessel to be Hanged to sup ort the same in true sha e, a Hanginghead s aft and a supporting evice for the outer end of the can on the outer end of said gagging head-shaft, substantially as speci- 4.
